Abstract

We analyzed an 6.7-year span of data from a rotating torsion-pendulum containing 1023\approx 10^{23} polarized electrons to search for the "wind" arising from ultralight, axionlike dark matter with masses between 102310^{-23} and 101810^{-18} eV/c2^2. Over most of this range we obtain a 95\% confidence limit Fa/Ce1×1015F_{\rm a}/C_{\rm e} \geq 1 \times 10^{15} eV on the axionlike decay constant.
